Stone Edge Surfaces Eastern Ledgestone vertical wall texture stamp set. The Eastern Ledgestone vertical wall texture stamp set is in our drystack stamp family and comes as a set of 4 stamps. The stamps are easy to use with each stamp having two handles for easy application control. Each stamp is approximately 12′ x 18″ in size and are meant to be rotated 180 degrees to double the pattern, so 4 stamps can give 8 looks. For best results, always rotate the order of the 4 stamps so you do not create a predictable pattern.
